What is the model mapper?

Model Mapper is a tool that helps you link the entities in your vehicle database to the vehicle model and make returned from the Parivahan system in RC Detailed API. 

How does the model mapper work?

The model works by matching the name of the maker+model returned in the RC detailed API, to the entities in your vehicle database - the "model master" file. Fuzzy logic is used to compare the string returned by RC Detailed API to the maker and model names in your database and pick the closest match. The highest ranked match is shared as a part of the RC Detailed response.

How to set up and use model master?

You have to share a master file that includes all vehicle makes and models in your database. This will be set up by Gridlines team and a mapping_id allocated to you. If the mapping_ID is then passed in a Fetch RC detailed request, the closest match from the master, along with any additional details in the master file, will be returned as part of the response in a "custom_data" object.
